Pap AD. The relationship between childhood sexual abuse experience and complaints of chronic pelvic pain and male's with sexual dysfunction [dissertation]. São Paulo: "Faculdade de Medicina, Universidade de São Paulo"; 2019. INTRODUCTION: Child sexual abuse is a universal phenomenon that affects all ages, social classes and cultures. In Brazil it is the second largest type of violence among children from 0 to 9 years old. Many studies point to the importance of evaluating the ocurrence of child sexual abuse in patients with sexual disfunctions and chronic pelvic pain, since the history of abuse increases the risc of presenting sexual problems in the adult life. Unlinke women, there are few studies that relate the experience of child sexual abuse and the development of utological complaints the affect male sexual function. OBJECTIVE: To evaluate the relationship of sexual abuse experience in childhood and chronic pelvic pain (CPP), erectile dysfunction (ED) and premature ejaculation (PE). METHOD: This is a cross sectional study. The sample consisted of eighty men, between 30 and 59 years old, patients of the Urological Clinic Dividion of the Hospital das Clínicas in São Paulo, Brazil. The patients presented chronic pelvic pain, erectile dysfunction and or premature ejaculation. Data were collected during one year. The history of childhood sexual abuse was assessed using the Childhood Sexual Experience Questionnaire, translated and tested for use in research. The type of abuse, people involved, age of onset and duration of abuse, sexual choice, marital status and risk factors (heart disease, hypertension, diabetes and psychiatric diseases) were also evaluated. Chi Square test was used to evaluate the categorical variables and univariate GLM to evaluate the continuous variables, represented by mean ± standard deviation. The continuous data were represented in absolute frequency and percentage (%). RESULTS: The sample was characterized by predominantly married and heterossexual men wich mean age of 50.2 years. The ED group presented a higher diabetes index compared to the CPP and PE groups. There were no statistical difference between groups in prevalence of abuse. The mean age at onset of abuse was 9.6 years. Most of the abuses lasted more than a year and in all episodes the person involved was known to the child. COCLUSION: The high prevalence of child sexual abuse in the sample reveals a problem in the notification of cases with the male gender. The stigma of child abuse, restricted concept of abuse (focused on serious cases), unprepared health professional in identify the cases. The literature indicates higher rates of abuse with the famale population. Even compared to these data, the prevalence of child sexual violence is higher in this research, reinforcing the hypothesis that the antecedente of sexual violence is a risk fator for the development of health problems which affect male sexuality.
